Be it known that I, MARCUS COLEGATE DANN, a resident of Minneapolis, in the county of Hennepin and State of Minnesota, have in vented certain new anduseful Improvements in a Process of and Apparatus for Setting Up Double stave Barrels, of which the following is a specification.

Thisinvention relates to aprocess and means for setting up double-stave barrels; and it consists in the construction and arrangement of parts hereinafter shown and described, and sought to be specifically claimed.

Figure 1 is a sectional elevation of a former with the staves set up within it, and Fig. 2 is a plan view of the same. Fig. 3 is a perspective view of the. former. Fig. 4: is a view of one of the barrels after being removed from shown in the drawings.

the former, inverted, and wedged up, ready for the completion of the trussing. Fig. 5 is a perspective view of a number of the staves detached, showing their relative positions when setup. Fig. 6 is an enlarged sectional view of a portion of the former, one of the truss-loops, and a pair of the staves, illustrating more fully their construction and relative positions. I

This invention relates to that class of barrels constructed of two sets of staves-one inside the other-the joints of the outer set breaking with those of the inner set, as Great difficulty has been heretofore experienced in setting up this style of barrel, because of the inability to easily and quickly tighten both sets of staves equally. Usually these barrels have been set up by the use of an inner former or plate and an outer ring or hoop, between which hoop and plate the two sets of staves are set up and the outer hoop or ring drawn tightly around the barrel to secure the staves. The barrels in this shape are then removed from the inner plate and the ends trussed in the ordinary manner This method of setting up the bar rel is objectionable for many reasons. First,

the inner plate being necessarily smaller than the interior of the barrel, when the outer hoop is tightened up, the inner set of staves are very likely to be bulged inward; second, both ends of the barrel require trussing separately; and, third, the apparatus in which the staves are set up is expensive and of no use except for this particular purpose. i

To avoid these objections and enable a barrel of this kind to be set up quickly and easily, and with no more likelihood of the staves failing to wedge up or be tightened than with an ordinary single-stave barrel,-is the object of my invention, which consistsin setting up the inner staves inside the outer staves in a complete circle, and with the inner set of staves projecting above the outer set a short distance, and then removing the barrel with the usual truss-hoops thereon, and forcing all the inner set of staves down into place even with the outer set at the same time, either" by pressure brought to bear in any suitable manner from above or by inverting the barrel and forcing it down upon the floor or other level place, to drive all the projecting inner staves up into place level with the outer set. This latter method is preferable, as being very simple and fully as effective as any other. By' this means every one of the inner staves is a wedge stave between those upon either side, and thus all the staves are held equally firm, andno danger exists of bulging if the staves are too large, as the pressure is equalized on the entire inner surface of the barrel. If the staves are too small, of course one large stave will have to be set into the'cirele; but this is no more troublethan is liable to occur in set ting up an ordinary barrel.

Any suitable former may be used in which i to set up the barrel, so that the inner set of staves project above the outer set; but I have found that an ordinary former in which singlestave barrels are set up, provided with an auxiliary raised disk or plate to support the lower ends of the inner staves and hold them up above the lower endsof the outer staves, answers the purpose admirably.

This construction is shown in the drawings, in whichA A are the outer staves, B B the inner staves, O O the truss-hoops, D the base of the former, and E the standards for supporting the upper. truss-hoop, G. D and standards E constitute the ordinary former for setting up common single-stave barrels; but to adapt it to setting up the doublestave barrels according to my invention, I form an auxiliary raised disk or plate, F, upon the to assist in holding the staves B and to give base D, the diameter of this auxiliary disk be 1 ing the same as the interior diameter of the outer set' of staves, A, so that the outer set will rest down on the base D, and the inner set will rest upon top of the outer edge of the surface of the auxiliary disk, as shown in Figs. 1 and 6. This auxiliary plate F may be made separate from the base D, or cast in one piece therewith, as shown. The outer upper edge of the plate F may be chamfered off, as shown,

them a square or nearly square support for their lower ends.

By this method of setting up the barrels I overcome the objections specified as existing. against the ordinary methodviz., danger of bulging avoided, only the ordinary trussing required, and dispensing with any extra apparatus, except the auxiliary plate F on the former, and even that in nowise interferes with the use of the former for setting up ordinary barrels.

Having described my invention and set forth its'merits, what I claim is- 1. The method, substantially as hereinbefore set forth, of setting and wedging up doublestave barrels, consisting in first setting up the barrel with the inner set of staves projecting above the outer set, and then forcing all of said projecting inner staves down level with the outer staves at the same time.

2. In a former for setting up double-stave barrels, the combination of the raised disk or ledge F, for supporting the inner set of staves at the proper height, with the base D, for supporting the outer set of staves, the standards E E, and hoop or belt 0, substantially as herein specified.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses. 1
